Adaptive fixed point arithmetic controller apparatus and method

ABSTRACT

Adaptive scaling circuitry connected to local scalars to accummulate digital shifts during calculations and associate the shifts with particular quantities involved. The circuitry also supplies shift commands to certain scalers so that calculations such as adding and subtracting can be performed. The shifting of digital words is performed so that optimum use of the number of bits in a word may be made. In complex computation systems the adaptive scaling takes the place of an AGC function throughout the computations.
